This band info really has made too many people believe New York is a possible setting. The fact that everyone, even huge GTA fans that know all the facts, have looked beyond is that Liberty City was based off New York. It's unlikely Rockstar would use New York again.
I mean personally, I would prefer a New York setting over say a London setting, but I really want something all new. New York has already been done with GTA and used too many times with other games.
